IMS Data in SAS Programs

Example of VALIDVARNAME=V7

The following is an example of a Version 7 or later update of data. The Version 7 or later data set, MYDATA.SSNUMS, is updated with data that is described by the view descriptor VLIB.SSNAME. Both the data in the data set and in the view descriptor are sorted by Social Security number before the output data set is used to update the existing data set.

To perform the update, you would enter the following statements:

proc sort data=mydata.ssnums;
   by soc_sec_number;
run;

proc print data=mydata.ssnums;
   title2 'MYDATA.SSNUMS Data Set';
run;

proc sort data=vlib.ssname out=mydata.newnums;
   by soc_sec_number;
run;

proc print data=mydata.newnums;
   title2 'Data Described by MYDATA.NEWNUMS';
run;

data mydata.newnames;
   update mydata.ssnums mydata.newnums;
   by soc_sec_number;
   run;

proc print data=mydata.newnames;
   title2 'MYDATA.NEWNAMES Data Set';
   run;

The new SAS data file MYDATA.NEWNAMES is a Version 7 or later data file that is stored in a Version 7 or later library associated with the libref MYDATA. The following three outputs show the results of the PRINT procedures for the original data file, the transaction data, and the updated data file.
